Abstract

A variation of fuel vaporizer for internal combustion engine is provided that includes an inlet guide vane assembly, and a turbine assembly, the turbine assembly being mounted between the carburetor and intake manifold of the internal combustion engine.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. In a variation of a fuel vaporizer for internal combustion engines, including a carburetor and an intake manifold, inlet guide vane assembly means carried in a discrete housing member and disposed below said carburetor and above said intake manifold and defined by an opening within said discrete housing member, plural stationary spaced vanes extending across said opening and obliquely angled relative to the direction of flow of fuel and air passing from the carburetor to the intake manifold supported by said housing member, turbine means disposed between said guide vane assembly means and said intake manifold wherein said turbine means includes an impeller embodying a hub, an internal bearing in said hub and a discrete turbine housing surrounding and supporting said impeller oriented in serial registry with said housing member and intake manifold, said inlet guide vane assembly means changes the flow direction of air and fuel before it impinges upon said turbine means to provide better atomization of fuel and a portion where said turbine housing communicates with said stationary vane housing defining a transition pressure area where air/fuel proceeds from a high pressure area to a low pressure area in said turbine housing for improved atomization by flash misting. 
     
     
       2. The structure as defined in claim 1 including a transition member interposed between said turbine housing and the intake manifold oriented in serial registry therebetween. 
     
     
       3. The device of claim 2 wherein plural spaced parallel vanes are disposed in said opening defining said inlet guide vane assembly means. 
     
     
       4. The structure as defined in claim 3 wherein there is provided a plurality of inlet guide vane assemblies with vanes therein, and wherein said assemblies are arranged in spaced apart parallel relation with respect to each other. 
     
     
       5. The device of each claim 4 in which the openings of said plural intakes are offset relative to an axis defined by said hub and stud. 
     
     
       6. The device of claim 2 including gaskets interposed respectively between said carburetor, housing member, turbine housing, transition member and intake manifold for sealing. 
     
     
       7. The device of claim 6 wherein said impeller has blades which are canted at 15 degrees from an horizontal plane. 
     
     
       8. The device of claim 6 wherein said inlet guide vane assembly includes a conical nose cone having a tapered leading edge facing up stream, and a plurality of radially extending stationary vanes having a compound contour for directing the air/fuel to said impeller. 
     
     
       9. The device of claim 8 wherein said stationary vanes having a leading edge canted 10° from a vertical plane and a trailing edge canted at 30° from a horizontal plane. 
     
     
       10. The structure as defined in claim 8 and further including a tail cone operatively connected to a lowermost portion of said impeller and placed in said transition housing, said tail cone having a tapered trailing edge. 
     
     
       11. The structure as defined in claim 10 wherein said inlet guide vane assembly is axially offset from said turbine means, said inlet guide vane assembly having vanes therein.
